Gibraltar Z9185-BEV Beveled Round Flat Washer 1/2 in Steel

Product Description

The GIBRALTAR Z9185-BEV is a beveled round flat washer designed for use with 1/2 inch screws and fasteners. Manufactured from 12L14 steel with a plain finish, it provides a smooth load-bearing surface that distributes clamping force evenly under fastener heads or nuts. The beveled profile allows it to seat flush against countersunk or angled surfaces. With a 17/32 inch inside diameter, 1 inch outside diameter, and 3/16 inch thickness, this washer meets standard inch-measurement specifications for mechanical and structural assembly applications. Licensed tradespeople and maintenance technicians working with bolted connections will find it suitable for a wide range of trade installations.

This washer is suited for use in mechanical, plumbing, electrical, and HVAC structural fastening applications where a beveled seating surface is required. It is appropriate for both light commercial and residential installations. The plain steel finish makes it compatible with assemblies where paint or coating will be applied after installation, or where an uncoated surface is acceptable for the service environment. The 1/2 inch screw size is one of the most common in trade work, making this washer a practical stock item for service vans and shop inventory.

Installation Notes

Installation is performed by the appropriate licensed trade professional depending on the application — HVAC, plumbing, or electrical. Ensure the mating surface is clean and free of debris before seating the washer. Do not overtighten fasteners, as this can deform the washer and reduce load distribution effectiveness. Verify material compatibility with the service environment before installation, as the plain steel finish offers no corrosion protection.
